If Kubernetes is the pilot that steers the ship, then Helm Charts are the navigational maps that guide the journey correctly. We have seen this happening over the years in the world of software development, one tool comes with an idea, serves the purpose, and becomes obsolete in some years, and then one more tool gets introduced that replaces the old approach, and this journey continues. Similarly, today is the era where Kubernetes is looked upon as the king of container orchestration. Backed by Google, Kubernetes has grown leaps and bounds by increasing its reach and community to every part of the world.

![](https://cdn.hackernoon.com/images/gv93oOBCpSQa2kRIURhv0A8fVP33-n11633ax.png)
DevSecOps is the new buzz and definitely a potential candidate to scare people in the ever-changing software industry. When I heard the term for the first time, my inner voice said it out loud, "When just this Happened, and why SEC is sandwich between them ?". Later on, to look cool, I started adding DevSecOps on my profile, but the dire consequence was a complete disappointment. DevSecOps isn't just restricted to understand security by heart & fit it with DevOps. A good analogy would be not to imagine your ex with someone, especially with your girlfriend/wife. It is all about "Shift left on Security" i.e. to introduce security as early as possible in the SDLC. Though I am not going to bore you with the definitions and concepts as I am a practical person. Thus, my objective here is to demonstrate how DevSecOps works in reality. The following series split into two parts (refer below) with very simple and clear instructions to provision a CI/CD pipeline adhering to DevSecOps principles in AWS. Everything covered from scratch you won't face any difficulty understanding. In case of any clarification, drop me a note on LinkedIn. Feel free to explore them with ease, skip to the one which is relevant to you.

![](https://cdn.hackernoon.com/images/2jqChkrv03exBUgkLrDzIbfM99q2-f582rch.jpeg)
Node.js monitoring is a tricky task. There are certain challenges to look out for. Because Node.js is a dynamically typed programming language and single-threaded you give the interpreter and runtime a lot of freedom to make decisions. This can easily result in memory leaks and high CPU loads. Parallel execution is simulated in Node.js by using asynchronous execution of functions. But, if a single function blocks the thread or event queue, the application performance will take a huge hit.
